A short educational YouTube clip (by Anne Truong MD) explaining that most erectile dysfunction (ED) — ~90% per the speaker — is due to physical/medical causes. The speaker identifies poor penile blood flow as the core problem, attributes poor flow to low nitric oxide produced by the vascular endothelium, and explains that nitric oxide causes blood vessel dilation and penile muscle relaxation necessary for erection.

What causes ED? The causes of ED? 90% is physical. When I say physical, it means from medical causes. What physical mean is that? Poor blood flow to the penis. And how do you get poor blood flow? You have. Poor blood flow is low nitric oxide. Nitrous oxide is a critical. Critical. It's a gas that's in your body, actually. That is produced by the lining of the blood vessel called the endothelium. I'll show you a picture of that. That what it does is that it opens up blood vessels and you need a nitrous oxide in order to increase blood flow, and you need nitrous oxide so your penis muscle can be relaxed.
